THREAD-GUIDE FOR SPINNING-MACHINES.

SPECIFICATION forming" part of Letters Patent No. 270,169, dated January2,1883,

' Application filed May 5,1882. (No model.)

i To all whom it may concern:

Be it known that I, THOMAS D. WILMAR'IH, of Providence, in the county ofProvidence and State ofRhode Island, have invented a new and usefulImprovement in Thread-Guides for Spinning-Machines, of whichthet'ollowing is a full, clear, and exact description.

My in veu t-ion consists in a revolving threadguide, having, the objectto relieve the thread or yarn of tension, so and breaking thereof, andto produce a more even and a stronger yarn, as hereinafter described andclaimed.

Reference is to be hadtto the accompanying drawings, forming a part ofthis specification, in which similar letters ot reference indicatecorresponding parts'in all thefigures.

Figure l is an elevation showing my improved thread-guide as applied touse. Fig, 2 is a sectional side view of the same. Fig. 3 is an elevationof my improvement, shown applied to that portion of a spinninganachineimmediately from which it receives its movement; and Fig. 4 is a sideview thereof.

A is the ordinary delivery or fluted bottom roll of a spinning-machine.I

D is the bobbin upon which the thread or yarn is wound, and U is thethread-guide,

placed upon the shaft 0 intermediately of theroll A and bobbin D. Thethread-guide G is its mid-length for the yarn, and attached to the shaftby a set-screw, a, or other means.

In operation the thread or yarn passes from the roll A over the guide 0,and from thence to the bobbin. The shaft 0 is to be revolved in thedirection opposite to the travel of the yarn, the effect being that thetwist is carried to the bite of the roll A, where it is most needed, andat the same time the thread or yarn is relieved of tension at the rollA, so that stietching and breaking is prevented, thereby avoiding wasteand making the yarn more even, stronger, and better.

It will be understood that one of the revolving guides 0 will be fittedin connection with each bobbinh For convenience of dofiing or removingthe bobbins ot yarn or thread when full, the entire device is to be soarranged that it'may be moved endwise, thereby allowing the bobbins tocome off between the whirls.

as to prevent stretching E is a beam, to which is bolted a bracket, J,supporting a standard, K, bolted to the latter and forming one of thebearings for the shaft a, carrying the guide 0.

K is one of the standards which support the fluted roll-shaft.

Around the shaft 0 ot' the guide 0 is placed a spring, 1), arrangedbetween the guide U and the standard K. The springs l), while enabl ngthe ready holdingot the bifurcated key D", inserted between the standardK and gear-wheel E when the guide 0 is slid to one side to permit thedotting of the yarn, as indicated in dotted lines in Fig. 3, will alsocause the automatic return of the guide 0, with its shaft 0, to itsoriginal position.

F G are intermediate gearing for transmitting motion from the gear-WheelH, ordinarily employed for driving the back rolls of thespinning-machine, to the gear-wheel E of the guide-shalt c'to drive theguide 0 in a reverse direction to the travel of the thread over thefluted roll A. The shafts of the wheels F G are supported in standardsI, bolted to side pieces of the frame of the machine, only one of saidstandards'being shown.

In shifting the guide (3, with its shaft 0, to permit the doffing of theyarn, the gear-wheel E is moved away tiom the standard or support K adistance equal to the width of the key D and thelatterinserted betweenthe said wheel and standard K and-caused to straddle the shaft 0, asseen in dotted bees in Fig. 3. The

gear-wheel E is recessed or countersunk on its outer side to receive thenut which is screwed upon the shaft c for securing the wheel thereon,asshown in dotted lines in Fig. 3.

Having thus described my invention, I claim as new and desire to secureby Letters Paten t- The combination of the roll A, the bobbin D, and thering and traveler with the shaft- 0,

carrying the guide (J, and gearing E F G H, u C

adapted to drive the shaft in an opposite direction. to the travel ofthe yarn, whereby stretching and breaking of the yarn is prevented,substantially as specified.
